The series was later picked up by Adult Swim for the United States market and began airing on April 16, 2006.

Adult Swim aired the last episode on April 29, 2007, replacing Eureka's dialogue and the final scene with Axel and the children with the shortened regular opening and ending themes.

A week later on May 6, they re-aired the episode with the original opening and ending content intact after complaints from viewers.
